The International Agency for Research on Cancer (IARC), the cancer agency of the World Health Organization (WHO), has evaluated the carcinogenicity of occupational exposure as a firefighter.
After thoroughly reviewing the available scientific literature, the Working Group classified occupational exposure as a firefighter as carcinogenic to humans (Group 1), on the basis of sufficient evidence for cancer in humans.
A summary of the final evaluations has now been published online in The Lancet Oncology. The detailed assessment will be published in 2023 as Volume 132 of the IARC Monographs.
